Three-dimensional optical profilometry analysis of surface states obtained after finishing sequences for three...

The operating protocols used for finishing composite resins are numerous and affect the success of filling from a mechanical, biological, and aesthetic point of view. The study determined the most favorable finishing for each of the composites considered. The three-dimensional optical profilometry examination was used to obtain qualitative and quantitative measurements of three hybrid composites. Tungsten carbide burs left irregularities harder to eliminate than those caused by diamond burs. Sof-Lex disks and the Enhance System gave good results for the three materials. Charisma presented a good surface regardless of polishing method used. Finishing Z100 and Prisma TPH required a special operating protocol as specified by the manufacturers. This study demonstrated that the finishing procedure for composite materials must be strictly followed to obtain optimal results. Profilometry proved to be an excellent method to study the surface roughness of samples.
